[A man with a rare disfiguring cutaneous manifestation of sarcoidosis].

A 42-year-old man with no relevant medical history presented with a painless, red, disfiguring skin lesion located on the nose. He was diagnosed with lupus pernio, a rare, cutaneous subtype of sarcoidosis which is relatively resistant to therapy and is associated with systemic sarcoidosis.

International eDelphi Study to Reach Consensus on the Methotrexate Dosing Regimen in Patients With Psoriasis.

Importance: A clear dosing regimen for methotrexate in psoriasis is lacking, and this might lead to a suboptimal treatment. Because methotrexate is affordable and globally available, a uniform dosing regimen could potentially optimize the treatment of patients with psoriasis worldwide.

Objective: To reach international consensus among psoriasis experts on a uniform dosing regimen for treatment with methotrexate in adult and pediatric patients with psoriasis and identify potential future research topics.

Towards More Shared Decision Making in Dermatology: Develop-ment of Evidence-based Decision Cards for Psoriasis and Atopic Eczema Treatments.

In shared decision making (SDM) patients and physi-cians make treatment decisions together based on the best available evidence and the values and preferences of patients. SDM is very suitable for use in dermatological practice, but is infrequently applied by dermatologists. To support the application of SDM in dermatology we developed Decision Cards: 1-page overviews of possible treatment options, for use during a patient-physician consultation.

The current extent of and need for shared decision making in atopic dermatitis and psoriasis in the Netherlands: an online survey study amongst patients and physicians.

Background: In shared decision making (SDM), patients and physicians work together to choose the best treatment option for an individual patient. Atopic dermatitis (AD) and psoriasis are particularly suitable for SDM, considering that the best treatment option depends on a patient's preferences and values (preference-sensitive decisions). Currently, it is unknown to what extent SDM is applied in treatment decisions for these diseases in the Netherlands.

Initial Results of Secukinumab Drug Survival in Patients with Psoriasis: A Multicentre Daily Practice Cohort Study.

Interleukin 17-antagonist secukinumab demonstrated high efficacy for treatment of psoriasis in randomized controlled trials. However, performance in daily practice may differ from trials. Drug survival is a comprehensive outcome covering effectiveness and safety, suitable for analyses of daily practice.

The validity, reliability and acceptability of the SAVASI; a new self-assessment score in vitiligo.

Background: Vitiligo is a common depigmenting skin disorder that can influence a patient's quality of life. Although patient-orientated medicine is an emerging concept, a self-assessment tool to assess the degree of depigmentation in vitiligo is not yet available. Therefore, we developed the SAVASI, a self-assessment tool that uses the same basic principles as the VASI.

Waterjet cutting of periprosthetic interface tissue in loosened hip prostheses: an in vitro feasibility study.

Waterjet cutting technology is considered a promising technology to be used for minimally invasive removal of interface tissue surrounding aseptically loose hip prostheses. The goal of this study was to investigate the feasibility of waterjet cutting of interface tissue membrane. Waterjets with 0.

Power generation based on biomass by combined fermentation and gasification--a new concept derived from experiments and modelling.

A new concept is proposed for combined fermentation (two-stage high-load fermenter) and gasification (two-stage fluidised bed gasifier with CO2 separation) of sewage sludge and wood, and the subsequent utilisation of the biogenic gases in a hybrid power plant, consisting of a solid oxide fuel cell and a gas turbine. The development and optimisation of the important processes of the new concept (fermentation, gasification, utilisation) are reported in detail. For the gas production, process parameters were experimentally and numerically investigated to achieve high conversion rates of biomass.

Mechanical properties of human bone-implant interface tissue in aseptically loose hip implants.

The main cause of failure in total hip replacement is aseptic loosening which is associated with the formation of a periprosthetic fibrous (interface) tissue. Despite important applications for finite element modeling of loose implants, the mechanical properties of the bone-implant interface tissue have never been measured in humans. In this study, we performed unconfined compression tests to characterize the mechanical properties of the interface tissue and to determine the parameters of various hyperelastic material models which were fitted to the measurements.

Comparison of Ho:YAG laser and coblation for interface tissue removal in minimally invasive hip refixation procedures.

Aseptic loosening is the major failure mode for hip prostheses. Currently, loosened prostheses are revised during open surgery. Because of a high complication rate, this demanding procedure cannot be performed in patients with a poor general health.

Measuring femoral lesions despite CT metal artefacts: a cadaveric study.

Objective: Computed tomography is the modality of choice for measuring osteolysis but suffers from metal-induced artefacts obscuring periprosthetic tissues. Previous papers on metal artefact reduction (MAR) show qualitative improvements, but their algorithms have not found acceptance for clinical applications. We investigated to what extent metal artefacts interfere with the segmentation of lesions adjacent to a metal femoral implant and whether metal artefact reduction improves the manual segmentation of such lesions.
